Hello there, I try to migrate but it was found that I had an older version of ISPConfig. during migration include errors with Mysql. Currently I have ISPConfig 3.0.5.3 version and update propose and New Version: 3.0.5.4p1. therefore we believe that the pheasants update of ISPConfig in the old server I could do my migration. Here are the questions I ask myself: "The update ispconfig deletes files and folders already created on the server?" "After the update ispconfig there will he a bug via Mysql?" I hope to have a good answer because I am a can in trouble.
Answer is no, when you do proper update method then ISPConfig don't delete files/folders. No there is no bug after update. To update ISPConfig follow this link method. Or manually you can upgrade as
